It's hard to find something profound to say about this braille map of Europe from World War I, but readers might be interested to know that the braille alphabet used in publications for the visually impaired actually developed out of the context of European warfare. Sonography, a system of writing using embossed dots on a piece of paper, was developed for use as a code for silent and nighttime communication in Napoleon's armies and later modified into the modern-day Braille alphabet by Louis Braille.
